reegle.info – linked (open) energy data cloud

Access to the latest high quality information on renewables, energy efficiency and climate change is fundamental to the acceleration of the clean energy marketplace, facilitating investments, promoting new legislation and regulations and broadening interest and knowledge in the sector.

As reegle.info provides relevant clean energy data from several key energy open data sources as for instance OpenEI, World Bank Data or the UK Open Data Portal the reegle.info Information Gateway has a strong need for efficient and automated data management mechanisms and technologies! Therefore REEEP (The Renewable Energy and Energy Efficiency Partnership) decided to use Linked Open Data (LODLinked Open Data (LOD) stands for freely available data on the World Wide Web, which can be identified via Uniform Resource Identifier (URI) and can be accessed and retrieved directly via HTTP. Finally link your data to other data to provide context.).

Linked Open DataLinked Open Data (LOD) stands for freely available data on the World Wide Web, which can be identified via Uniform Resource Identifier (URI) and can be accessed and retrieved directly via HTTP. Finally link your data to other data to provide context. provides a powerful way for reegle.info for sustainable data management and data integration – thereby the current reegle.info linked (open) energy data cloud came into being and looks as follows:

The figure of the reegle.info linked (open) energy data cloud above shows the model behind the scenes of the reegle.info clean energy information gateway providing an insight about sources and respective connections / links between the several sources and data sets.

For the realisation of the Linked Open Data based reegle.info system the following software components are in use:
